>>508519820 (OP)>AIThe aggressor's response, attributing the other culture's dislike to an inherent nature to hate, is a key element of cognitive dissonance reduction. They've experienced a conflict: their actions (the cultural deconstruction) created a negative reaction, but they don't want to accept responsibility. Attributing it to inherent nature simplifies the situation, allowing them to maintain a positive self-image and avoid acknowledging the impact of their behavior.
The 'inherent nature' claim serves to justify the aggressor's actions. It's a form of externalization, blaming the victim for their reaction. If they're inherently hateful, then the other culture's anger is simply a predictable outcome, not a consequence of the aggressor's actions.
Once the aggressor has adopted the inherent hatred explanation, they are likely to seek out and interpret information that confirms this belief, while dismissing evidence to the contrary.
The aggressor's group likely shares this perspective, reinforcing it through social pressure. Social Identity Theory suggests people derive part of their identity from their group membership. When their group is perceived as being disliked, it threatens that identity, so they seek explanations that minimize the group's responsibility and emphasize the "othering" of the opposing group.
